【摘要】：目的探討某集團公司近10年來塵肺發(fā)病情況,分析其發(fā)病特點及流行特征,為企業(yè)職業(yè)病防治提供參考依據(jù)。方法對2002-2011年底健康監(jiān)護資料中新診斷為塵肺壹期47人,分析其發(fā)病率、發(fā)病年齡、工種、接塵工齡、粉塵濃度關(guān)系進行比較分析。結(jié)果該公司2002-2011年礦山開采工作面粉塵濃度由2.89 mg/m3下降至1.80 mg/m3,冶煉反射爐粉塵濃度由7.95 mg/m3下降至3.50 mg/m3。塵肺發(fā)病率從4.35‰下降至1.08‰,其中矽肺的發(fā)病率由7.96‰降至1.40‰,冶煉工塵肺發(fā)病率在0.29‰~2.08‰。塵肺總患病率為8.47‰,其中矽肺、冶煉工塵肺患病率分別為14.02‰、4.99‰(P0.01)。矽肺、冶煉工塵肺發(fā)病年齡分別為(49.20±5.80)歲、(45.50±5.90)歲(P0.05);接塵工齡分別為(18.70±5.60)年、(14.80±4.70)年(P0.05)。鑿巖工、其他輔助工矽肺發(fā)病年齡分別為(45.60±5.50)歲、(49.60±6.70)歲(P0.05);接塵工齡分別為(15.65±3.50)年、(18.25±6.20)年(P0.05)。不同年限矽肺發(fā)病年齡、接塵工齡差異無統(tǒng)計學意義;不同年限冶煉工塵肺發(fā)病年齡、接塵工齡差異無統(tǒng)計學意義。結(jié)論該集團公司生產(chǎn)性粉塵濃度逐年下降,矽肺發(fā)病率下降明顯。矽肺發(fā)病率比冶煉工塵肺發(fā)病率高,但冶煉工塵肺發(fā)病年齡比矽肺發(fā)病年齡小,冶煉工塵肺接塵工齡比矽肺短,這是否與冶煉工接觸的粉塵類型等因素有關(guān),需進一步研究證實。
[Abstract]:Objective to investigate the incidence of pneumoconiosis in a group company in the past 10 years, and to analyze the characteristics and epidemic characteristics of pneumoconiosis in order to provide reference for the prevention and treatment of occupational diseases in enterprises. Methods 47 newly diagnosed pneumoconiosis patients from 2002 to 2011 were analyzed. The incidence, onset age, type of work, length of exposure to dust and dust concentration were compared and analyzed. Results from 2002 to 2011, the dust concentration of mining face decreased from 2.89 mg/m3 to 1.80 mg/m3, from 7.95 mg/m3 to 3.50 mg/m3.. The incidence of pneumoconiosis decreased from 4.35 鈥，
